 403 <p >General Purpose Input/Output (GPIO) API. </p>
 404 <p >RP-series microcontrollers have two banks of General Purpose Input / Output (GPIO) pins, which are assigned as follows:</p>
 405 <p >All GPIOs support digital input and output, but a subset can also be used as inputs to the chip’s Analogue to Digital Converter (ADC). The allocation of GPIO pins to the ADC depends on the packaging.</p>
 406 <p >RP2040 and RP2350 QFN-60 GPIO, ADC pins are 26-29. RP2350 QFN-80, ADC pins are 40-47.</p>
 407 <p >Each GPIO can be controlled directly by software running on the processors, or by a number of other functional blocks.</p>
 408 <p >The function allocated to each GPIO is selected by calling the <a class="el" href="group__hardware__gpio.html#ga22f6b90c4c7e0013b4b5341de0a44fc4">gpio_set_function</a> function. </p><dl class="section note"><dt>Note</dt><dd>Not all functions are available on all pins.</dd></dl>
 409 <p>Each GPIO can have one function selected at a time. Likewise, each peripheral input (e.g. UART0 RX) should only be selected on one <em>GPIO</em> at a time. If the same peripheral input is connected to multiple GPIOs, the peripheral sees the logical OR of these GPIO inputs. Please refer to the datasheet for more information on GPIO function select.</p>
